Man, ads are great. They allow content to be targeted towards people that could potentially not afford the content and towards people that might not necessarily use the product normally. The world is already significantly divided by wealth. Assuming someone poor even has access to a service like Google, imagine if it was behind a paywall. Could they afford it? If not imagine how much of a life advantage someone wealt…
The whole point of ads is to convince people to buy things that they may otherwise not. That seems like the opposite of helping poor people. Also, if you are struggling financially, ad supported "content" is probably not a major concern in your life, and certainly not a solution to your problems.
Additionally ad targeting means they might see adverts for things they could afford and that's t be relevant to their life instead of things meant for rich westerners.
The whole mental confusion between advertising and privacy in the technical and media community is really irritating. What's the alternative to advertising? Direct payments. And how do you do those? Credit cards. And what do credit cards have on them? Your legal name and your physical address. And how do they work? You provide those details to the seller.
Good luck using Tor or even incognito mode on a an without adverts.
